The EMMAR 120 3B is a V-belt pulley with a 120 mm diameter, three grooves, and section B. It is manufactured in-house by MR Industrial Accessories, so dimensions and features can be tailored to your mounting needs. Use it to transfer motion between parallel shafts in industrial machinery where a fixed ratio and straightforward maintenance are required.

This pulley has a 120 mm diameter, three grooves, and section B. Section B corresponds to classic-profile V-belts, suitable for medium power. With three grooves, you can run up to three belts in parallel, which distributes the load and improves transmission. The 120 mm diameter sets the speed ratio when paired with the driven pulley. The pulley is made of cast iron or machined steel, depending on the application, and is balanced to rotate without vibration at normal working speeds.

Typical applications include machine tools, compressors, fans, pumps, conveyor belts, and process equipment. You will also find it in agricultural machinery and maintenance workshops. It is common in setups where the speed of a motor shaft needs to be changed to a driven shaft at a fixed ratio with minimal maintenance. The three grooves give you flexibility to adjust transmitted power by the number of belts installed.

When selecting this pulley, consider the pitch diameter, number of grooves, and belt section. Check that the keyway and shaft bore match the motor or machine. Proper balancing and alignment with the driven pulley are essential to prevent irregular belt wear. If space permits, choose a larger diameter to reduce stress on the belt. Section B accepts standard profile B belts.

If you need a different number of grooves, another diameter, or a different section, custom manufacturing is available. To request an equivalent, provide the full part number, section, number of grooves, and diameter. The original pulley's part number or a photo also helps. With that information, we can identify the part within our in-house manufacturing line.
